-- The enriched uranium rod driven EU generator.
-- A very large and advanced machine providing vast amounts of power.
-- Very efficient but also expensive to run as it needs uranium. (10000EU 86400 ticks (24h))
-- Provides HV EUs that can be down converted as needed.
--
-- The nuclear reactor core needs water and a protective shield to work.
-- This is checked now and then and if the machine is tampered with... BOOM!

local power_supply = 10000 -- [HV] EUs
local fuel_type = "technic:enriched_uranium" -- This reactor burns this stuff
-- FIXME: recipe must make more sense like a rod recepticle, steam chamber, HV generator?
